Definition: What is "Aortic valve stenosis"?


Aortic valve stenosis (AS) is a "valvular" heart disease caused by the incomplete opening of the aortic valve. Normally, the aortic valves control the direction of blood flow from the left ventricle to the aorta. When the aortic valve is in good working condition, it does not obstruct the flow of blood. Aortic valve stenosis is a common disorder, affecting about 2% of individuals over 65 years old, 3% of patients over 75 & 4% of people over 85 years old. Since the global population is aging, the prevalence of Aortic valve stenosis is increasing.

Symptoms & Signs

When aortic valve stenosis is symptomatic, patients may experience angina, dizziness, syncope (fainting spells) & congestive heart failure. If aortic valve is not replaced, congestive heart failure accounts to a two-year mortality rate of 50%, syncope accounts for a three-year mortality rate of 50% & angina has a five-year mortality rate of 50%. Aortic valve stenosis is associated with colon angiodysplasia. This condition also causes Von Willebrand disease.

Treatment: How to Treat "Aortic valve stenosis"?

Aortic valve stenosis can be treated with various medications to control symptoms. However, surgery is the primary cure for this condition. An aortic valve replacement is done if medications do not control symptoms. For infants & children, balloon valvuloplasty is an effective method to cure Aortic valve stenosis.
